A Calgary man who repeatedly sexually assaulted two young girls at a city day home has been granted day parole.

David Watkins will stay at a halfway house during his parole, but the parole board didn't say where the house is located.

Watkins was sentenced to four years in prison in September 2009 after pleading guilty to two counts of sexual assault only involving two young girls at an unlicensed child-care service run by his wife in Silver Springs.

At the time of his sentencing, provincial court Judge Allan Fradsham said Watkins, then 67, had violated a trust that demanded a significant sentence. He ended up being granted day parole a year and a half later.

At the parole hearing at Bowden Institution, a federal penitentiary north of Calgary, Watkins said he's been taking sex offender courses. But he acknowledged that he could still have a problem if left alone with children.

In addition to the prison time, Watkins has been prohibited from working or volunteering with children for 20 years.

The case sparked child-care advocates to call for stricter regulations on unlicensed child-care facilities.
